Starts a timer
timer_start/2 starts a timer and sets the elapse time to MilliSeconds milliseconds. If it has already been started, then it will be stopped and restarted with the new elapse time. When the timer elapses, the callback predicate, that has been defined, when creating the timer (see timer_create/2), will be called (if it is not 'null').
